The Medusa Nebula is a planetary nebula in the constellation of Gemini. It is also known as Abell 21 and Sharpless 2-274. It was originally discovered in 1955 by University of California, Los Angeles astronomer George O. Abell, who classified it as an old planetary nebula. [4]

The Eskimo Nebula is a bipolar double-shell planetary nebula in Gemini. It was discovered by the German-born British astronomer William Herschel on January 17, 1787, who thought it was a “star 9th magnitude with a pretty bright middle, nebulosity equally dispersed all around.”

2022年11月13日 · The Medusa Nebula (Sh2-274) is a large planetary nebula located 1,500 light-years away in the constellation Gemini. With an apparent magnitude of 15.99, the nebula is a challenging target for amateur telescopes. It occupies an area 10.25 arcminutes across and has a physical diameter of about 4 light-years.

Gemini is one of the constellations of the zodiac and is located in the northern celestial hemisphere. It was one of the 48 constellations described by the 2nd century AD astronomer Ptolemy, and it remains one of the 88 modern constellations today.

The Jellyfish Nebula (IC 443) is a supernova remnant located in the constellation Gemini. This nebula is approximately 5000 light-years from Earth and is estimated to be roughly 70 light-years in size. In the wide-field telescopic view below, you’ll notice two bright stars, Tejat, and Propus (Tejat Prior). The locate the Jellyfish Nebula with ...

Gemini, the twins, is a zodiac constellation representing the mythological twins Castor and Pollux. It is known for its bright stars, Castor and Pollux, and its prominent place in the winter sky.

NGC 2371 lies about 4,300 light-years away in the constellation Gemini. The Hubble image reveals several remarkable features, most notably the prominent pink clouds lying on opposite sides of the central star.

Gemini is also home to several interesting deep-sky objects, including star clusters, nebulae, and galaxies. These celestial wonders add to the allure of the constellation and provide opportunities for observation and study by astronomers and stargazers alike. Figure 1. IAU chart of Gemini.

NGC 2371 is a Planetary Nebula in the Gemini constellation. NGC 2371 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its visual magnitude of 11.2, NGC 2371 is visible with the help of a telescope having an aperture of 6 inches (150mm) or more
